Abstract: A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. Macroinstruction pipelining is employed (instead of microinstruction pipelining), with queueing between units of the CPU to allow flexibility in instruction execution times. A wide bandwidth is available for memory access; fetching 64-bit data blocks on each cycle. A hierarchical cache arrangement has an improved method of cache set selection, increasing the likelihood of a cache hit. A writeback cache is used (instead of writethrough) and writeback is allowed to proceed even though other accesses are suppressed due to queues being full. A branch prediction method employs a branch history table which records the taken vs. not-taken history of branch opcodes recently used, and uses an empirical algorithm to predict which way the next occurrence of this branch will go, based upon the history table. A floating point processor function is integrated on-chip, with enhanced speed due to a bypass technique; a trial mini-rounding is done on low-order bits of the result, and if correct, the last stage of the floating point processor can be bypassed, saving one cycle of latency. For CAL type instructions, a method for determining which registers need to be saved is executed in a minimum number of cycles, examining groups of register mask bits at one time. Internal processor registers are accessed with short (byte width) addresses instead of full physical addresses as used for memory and I/O references, but off-chip processor registers are memory-mapped and accessed by the same busses using the same controls as the memory and I/O. If a non-recoverable error detected by ECC circuits in the cache, an error transition mode is entered wherein the cache operates under limited access rules, allowing a maximum of access by the system for data blocks owned by the cache, but yet minimizing changes to the cache data so that diagnostics may be run. Separate queues are provided for the return data from memory and cache invalidates, yet the order or bus transactions is maintained by a pointer arrangement. The bus protocol used by the CPU to communicate with the system bus is of the pended type, with transactions on the bus identified by an ID field specifying the originator, and arbitration for bus grant goes one simultaneously with address/data transactions on the bus.

Abstract: The invention proposes a pressure plate arrangement for a motor vehicle friction clutch in which an adjusting device (19) which automatically compensates for the wear of the friction linings (21) is arranged in the path of support between a diaphragm spring (13) and a pressure plate (11) clamped against a flywheel (1) via friction linings (21) of a clutch disc (23), by the diaphragm spring (13). The adjusting device (19) has a wear travel compensating element (31) which automatically compensates for any play between the diaphragm spring (13) and the pressure plate (11), this compensating element taking the form of a radially resilient taper ring for example. Distributed circumferentially around the pressure plate are a number of play sensors (37). These are guided in a manner which allows axial movement and are locked by friction force (for example by self- locking). The play sensors (37) rest against the flywheel (1) or the clutch housing (9) firmly connected to the latter and have levers (43) which limit the maximum wear compensation travel of the compensating element (31). As a result, wear compensation takes place within the clutch and, what is more, independently of any wear compensation mechanisms of a hydraulic clutch release system. Moreover, the diaphragm spring (13) of the pressure plate arrangement proposed retains its initial position relative to the flywheel (1) or the clutch housing (9) irrespective of any wear compensation. <IMAGE>

Abstract: Large characters and numerals of a lapse time, a musical program title, or the like of a musical program under the performance recorded on a photomagnetic disc can be displayed, and an inadvertent erase of a musical program can be prevented. The TNO and lapse time of each musical program during the performance are displayed on a display unit as shown in Fig.3 at (f). Under this condition, when a title key is depressed, the title for the TNO is displayed for a predetermined time period on the display unit as shown in Fig.3 at (g). After the predetermined time period, the lapse time for the TNO is displayed as shown in Fig.3 at (h). When an erase key is depressed during the performance of a musical program, a controller erases the disc management information and additional information for the TNO from a RAM storing U-TOC information, and renumbers other TNOs to update the contents of RAM. Upon depression of a tray open key of a key matrix, the controller instructs an MD record/reproduction unit to stop the reproduction and copies the management information and additional information for the TNO stored in RAM to another RAM and records the copied information to a U-TOC area of a mini disc. Thereafter, the MD record/reproduction unit operates to eject out the disc cartridge.

Abstract: A transmission scheme serially propagates time slot data to a plurality of TSI modules (32) with time slot data contained in one TSI frame being serially transmitted from module to module in a daisy-chain technique. A dedicated outbound transmission bus (48) transmits the frame of data from one module to a dedicated inbound transmission bus (46) of another module. The outbound and inbound data buses are connected by separate buses on a backplane (34) which is coupled to each of the TSI modules. Preferably, the TSI modules do not transmit selected ones of the stored data to end destinations until the last TSI module has received the frame of data so that all modules can begin the transmission in time synchronization. Maximum transfer data rates can be achieved since undesired transmission line characteristics or disruptions are minimized by the use of dedicated input and output transfer buses between the modules. Additional modules can be added without disrupting the transmission data rate between existing modules, thereby permitting a growable TSI facility without adversely impacting the data transmission rate between modules.

Abstract: A scanning confocal microscope scans a sample with an incident beam of radiation, in a raster scan pattern, causing the sample to fluoresce and emit visible radiation in at least two wavelengths. A portion of the fluorescent light retraces a portion of the path optical of incident beam, to a dichroic mirror that separates it from the incident beam for detection by a pair of photomultiplier tubes. A data processor accumulates digital data from the photomultiplier tubes to form a succession of image data frames of the sample being scanned, in the two wavelengths. Image data for a selected number of frames in each wavelength is averaged and then recorded on a single track of a recording system, in an alternating fashion with averaged data for the other wavelength. In addition, a ratio of the averaged data for the two wavelengths is delivered to a video display.
